Many American women are earning money outside their homes today. Among women who are eighteen to sixty-four years old, fifty percent have jobs.
In general, working women have had more education than those who stay at home. Of course who work, thirty two percent have attended college, compared with twenty percent of those who do not have jobs.
Among women with jobs, eight out of ten drive a car to work, and eight percent take a vacation (假期) away from home during the past year. Much of the traveling is by air.
These figures come from a report which was written for advertisers(广告者). It offers a new picture of women today. For instance, it tells advertisers that fifty-one percent of all American women have traveled by air--along with fifty-nine percent of all American men.
The lesson for American business is that many women now have other interests besides their homes. They like advertisements which show women in office, planes and cars.
